HoYoverse’s sci-fi RPG is about to spin up its next chapter. Honkai: Star Rail Version 4.5, dubbed “To Roll the Stars in Astropolis,” is scheduled to go live tomorrow, and — as always — the exact moment it lands depends on which server you call home.
Here’s the schedule to mark down:
- NA server: August 25, 2026 at 11:00 PM ET (UTC-4)
- EU and Asia servers: August 26, 2026 at 11:00 AM (UTC+8)
The staggered rollout is standard fare for HoYoverse updates, with the update files unlocking in waves so trailblazers across regions can jump in around the same practical window. And yes — as with every Star Rail patch, the whole thing is completely free for the free-to-play title.
There’s one wrinkle worth flagging for anyone who plans their pulls and stamina spending around the calendar: version 4.5 runs for five weeks instead of the usual six-week cadence. That compressed schedule means banner phases and limited-time events will move a little faster than you might be used to, so anyone chasing rewards should plan accordingly rather than assuming the familiar six-week runway.
The headline draw, of course, is the roster. Version 4.5 introduces two new 5-star characters:
- Robin • Summeretto — a Remembrance-path unit aligned with the Wind element.
- Aventurine • Waveflair — an Elation-path character built around Quantum.
Both names carry a distinctly seasonal flavor that fits the Astropolis theme, and the pairing of Remembrance and Elation gives team-builders fresh options for summon-based and follow-up-heavy compositions. Robin returning in a Wind-flavored Summeretto variant and Aventurine reappearing as a Quantum-tuned Waveflair should give returning players plenty to theorycraft over the coming weeks.
If you’re planning to be online the second the servers open, keep an eye on your storage and download queue ahead of time — HoYoverse updates tend to be sizeable, and pre-loading before the maintenance window closes is the fastest route into the new content. Beyond that, the usual post-update routine applies: expect fresh Warp banners, event stages, and the accompanying spread of login rewards and free materials that accompany a major version bump.
With the shorter five-week window in play, Version 4.5 is shaping up to be a brisk, character-forward chapter. Set your alarm for the launch time in your region, top off your Stellar Jade, and get ready to roll the stars in Astropolis.
